Description of the invention (1) The present invention is generally about the technology of an electrical connector and it will be related to the use of a complementary connector for combining and locking. Lock the electrical connector. The combined connector usually includes an insulating housing in which a plurality of terminals or joints are installed, respectively. When these terminals or joints are combined, electrical connectors are connected to each other. For example, the joint connectors may be male and female connectors or plug and socket connectors to electrically connect the terminals or connectors therein. In some cases, the connectors have an interconnection locking mechanism that locks the connectors together when combined. In the past, the locking mechanism of electrical connectors has caused many problems, because they increase the power that must be used to couple or separate the connectors and interconnect each other. Therefore, the connectors have been designed to When the connectors are combined, the locking mechanisms are easily connected automatically, and different connecting devices can be moved into position after being combined, making it difficult to separate the mechanisms. However, so far, this system has been quite complicated and the cost is not very low, because of the number of components required. This is particularly true in hooded electrical connectors that also require most shielding elements. The present invention is about providing a lockable electrical connector to solve the above-mentioned problems, which is quite uncomplicated, includes fewer components, and is more cost-effective than conventional lockable electrical connectors. Therefore, one object of the present invention is to provide a new and better lockable electrical connector for combining and locking a complementary connector. In one of the embodiments shown in the present invention, the connector can be integrated along the base of this paper. The paper standard is applicable to the Chinese National Standard (CNS > A4 specification (210X297mm) (please read the precautions on the back before filling this page)

The A7 B7_ printed by the Beigong Consumer Cooperative of the Central Bureau of Economic Development of the Ministry of Economic Affairs 5. Description of the invention (5) It is made of conductive metal sheet. Each lock arm includes a first section 30a that extends substantially along the chopstick and extends from the outer side of the outer cover 34, a free end section 30b having a latch protrusion 36, and a first section 30a and the free end that extend The transition section 30c between and at an angle between the sections 30b = the latch protrusion 36 is formed by punching out the free end section 30b and protruding outward. The latch 36 is roughly triangular, but its true shape is determined according to the holding design requirements of the insertion and extraction force. In detail, by making a shallow bevel on the front edge, the insertion force It can be reduced and an angle on the rear edge will allow the latch to be positioned more reliably. The acute angle will not significantly increase the force required for separation because, as described below, the lock arms 30 are generally free to bend when separated but are limited when combined. The inwardly facing flange 38 projects inwardly from the rear of the housing 34 to help maintain the housing in position after the connector is assembled. In detail, upon separation, force will pull the lock arms and the outer cover will be opposed by contacting the convex line 38 behind the cover 22. A plurality of axially extending ribs 40 are formed or extruded in the cover 34 so as to protrude inward, the purpose of which will be described below. A large number of holes 41 are formed in the housing 34 to allow plastic to flow through when weaving the skeleton 24, as described below: Figures 3 and 4 show the start when manufacturing a lockable electrical connector 10 Steps, in detail * Most terminals or connectors 42 are connected to the conductor 48 of the wire 18 of the cable 16 by, for example, soldering.

Printed A7 _B7_ by the Beigong Consumer Cooperative of the Central Bureau of Economic Affairs of the Ministry of Economic Affairs 5. Description of the invention (6) The shape of the conductive cover 22 (Figure 1) can be fixed around a part of the housing 44 (Figures 3 and 4) ) 'In more detail' the conductive cover is a two-piece housing and includes a lower half 50 with a housing 44 assembled inside, as shown in Figure 5. The lower half of the hood is stamped and formed from a conductive gold hurricane sheet and includes a pair of curling arms 52 'as shown in Figure 5' when the hood is folded back over a part of the electrical desert ' The curl surrounds the inner cover 54 of the cable 16. If necessary, a crimp clip can be used as is conventional. Once the terminals located at the end of the housing 44 and at the ends of the wires 18 are inserted into the lower half 50 of the cover 22 and crimped at the cable At 16, the upper half 56 of one of the covers is combined to form the bottom half, as shown in Figures 7 and 8. Similar to the bottom half, the upper half 56 of the cover is made of conductive metal sheet punching and forming, and the complementary connection card _60 (Figure 8) and the bottom half on the top half The latch 60 of the portion 50 is snap-fitted to hold the two halves of the cover in a combined state around the shell 44 and the terminal 42 and crimped onto the cover 54 of the cable 16. The next step of the combination lockable electrical connector 10 is shown in Figures 9 and 10, in which the outer cover 34 (with the majority of the locking arms 30) is combined above the rear end of the cover 22 in the direction of an arrow "C" (Figure 9 ). When the outer cover 34 is positioned on the cover 22, the flange 38 of the outer cover abuts the rear end of the cover, and the inwardly projecting rib 40 of the outer cover forms an interference fit with the cover. Since the cover and the cover are made of conductive gold sheets, the cover and the cover are electrically common. The protruding ribs 40 not only provide an interference fit between the cover and the outer cover, but they also increase the area of pressure and apply the Chinese National Standard (CNS) A4 specifications (210X297) at the original paper size of the cover and the outer cover Mm) (Please read the notes on the back before filling this page)

The next step in manufacturing the lockable electrical connector is to insert-mold the skull 24 around the rear ends of the outer cover 34 and the cover 22, as shown in FIG. 11. It can be seen that although the body completely surrounds the outer cover and the curled area between the cover and the electrowrap 16, the lock arms 30 protrude forward from the insert-molded body and can be in the direction of the double arrow "D" Free bending 'Although the body rigidly fixes the cover 22, the outer cover 34 and the inner housing 44 are in a rigidly combined state. The body is molded to form a pair of spring-receiving pockets 62 and spring-supporting protrusions 63. The spring-supporting protrusions 63 combined with the recesses 62 provide a substantially circular support wall 68 even if the spring 64 is exposed to the body 24 The same is true when the outside is on its opposite side. 'The final step of assembling the lockable electrical connector is shown in FIG. 12, a pair of coil springs 64 are positioned against the circular support wall 68 and the spring-receiving pocket on the opposite side of the insert molded body 24 Within 62, as shown in Figure 12. The single-piece support member or cover 26 then slides through the above subassembly in the direction of arrow "E" (Figure 12). When the support member is positioned, as shown in Figure 13, the coil spring can be effective Ground is held in these recesses. In detail, please refer to FIG. 13 separately, the slidable support member 26 includes a majority of inner spurs 66 against which the front end of the coil spring 64 abuts * the rear ends of the springs abut against the body 24 in A circular spur 68 behind these pockets 62. Therefore, the springs bias the support member forward (Figure 13) in the direction of arrow "F", so that the support arms 28 projecting forward from the support member are immediately outside the lock arms 30. In essence, these support arms 28 prevent -10-This paper uses the Chinese National Standard (CNS) A4 specification (210X29 * 7mm) (please read the precautions on the back before filling in this 1)

Α7 Β7 The Ministry of Economic Affairs, Central Bureau of Preparing and Consuming Duty Printing and Duty Printing V. Description of the invention (8) The locking arms 30 are bent by the coupling shaft of the connector and most of them are bent outwards. There are a plurality of recesses 65 on both sides near the rear end thereof to accommodate the spring support protrusions 63 of the body 24. FIG. 13A shows that the slidable support 26 has an inclined abutment protrusion 70 on its inner side and the insert-molded body 24 has a relatively inclined abutment protrusion 72 on its outer side. When on the body, these convex inclined surfaces cross each other and engage with each other on a junction surface 74 to join each other. When the support member 26 is in the forward biased position, as shown in Figures 13 and 13 A, this abutment surface forms the forward limit position of the member when biased by the coil spring 64. The forward position is the slidable support member, wherein the support arms 28 are reduced to prevent the lock arms 30 from bending outward from their locked positions. As shown in the figure. Figure 14 shows that the support member or cover 26 that has moved backward in the direction of arrow "G" presses the coil spring 64 to the position where the flanges 76 abut the front end of the insert molded body 24, which forms the support member After the extreme position, it can be seen in Figure 14 that the support arms 28 have moved backwards away from the lock arms 30. Therefore, the lock arms can be freely bent outward in the direction of the arrow "H" and allow the lockable electrical connector 10 and the complementary connector 12 to separate from each other with a much smaller separation force than the support arms 30, As shown in Figure 13. For this purpose, it can be seen that the latch protrusion 36 on the inner side of the lock arms is inclined, downwardly inclined or triangular with respect to the coupling axis of the connectors in order to allow the connectors to be combined quite easily Or separate. Of course, when the slidable support member 26 is in its forward locking position as shown in FIG. 13, the support arms 28 prevent the lock arms from being locked from their locked positions -11-(please read the back Please fill out this page again.)-Binding-The paper size of the book is not in line with the Chinese National Standard (CNS) Α4 specification (210Χ297mm).
